Description:
BILIN B2 PU FOAM—easy to apply with a foam gun or straw. Expands and cures upon air exposure, forming durable, fire-safe seals compliant with DIN 4102 B2 standards. This flame-retardant material ceases burning instantly when fire is removed, ensuring superior safety. Perfect for insulation, gap filling, soundproofing, and sealing joints to block smoke and gas penetration. Offers strong bonding, fixing, and thermal/acoustic insulation properties. The CFC-free, environmentally friendly formula is versatile for construction applications, including crack sealing and structural reinforcement. Provides reliable performance for both residential and industrial projects.
